QPECIPICATION forming part of Letters Patent No. 378,704, dated February28. 1888 7 Application filed August 24, 1885. Serial No. 175,142. (Nomodel.)

To aZZ whom it may concern:

Be it known that we, CHARLES L. MEAD, ofNew York, in the county of NewYork and State of New York, and J USTUS A. TRAUT, of New Britain, in thecounty of Hartford and State of Connecticut,both citizens of the UnitedStates, have invented certain new and useful Improvements inBench-Planes, of which the following is a specification.

Our invention relates to improvements in adjusting the plane-ironslaterally.

In the accompanying drawings, Figure 1 is a vertical section, partly inelevation, of a bench-plane which embodies our invention. Fig. 2 is aplan View of the same with the holding-cap removed. Fig. 3 is a faceView of a portion of the frog and the laterally-adjusting lever. Fig. 4is a vertical section, partly in elevation, showing a modification ofour invention; and Fig. 5 is a face view of a portion of the frog andlaterally-adjusting lever of the plane represented in Fig. at.

\Ve have illustrated our improvement as applied to a Bailey plane, inwhich the cutter is adjusted up and down by means of the lever A and thenut B; but it may be used in connection with planes having differentmechanism for adjusting the cutter up and down. At the upper end of thefrog C we pivot the laterally adjusting lever D, the handle of whichlies under the upper end of the cutter E. On the short end of this leverthere is an upwardlyprojec-ting pin or stud, a, the length of which pinis longer than the thickness of the cutter E and nearly equal to thecombined thickness of the cutter E and the cap-iron F. In use thiscap-iron and cutter are secured together by a screw in the ordinarymanner. The cap-iron F is provided with a T-shaped slot, (shown mostclearly in Fig. 2,) the transverse portion of which slot receives theupper end of the adjusting-lever A, while that portion of the slot whichextends longitudinally with the cap-iron receives the upper end of thepin a. Inasmuch as the cap-iron has but a very slight up-and-downmovement, the slot for this pin can be made quite short. By turning thelever B to the right or left, as

may be required, the upper end of the capiron and cutter may be carriedto either side, so as to bring their edges square with the stock.

In Figs. 4 and 5 we have shown a modification of our invention, in whichwe have a similar lever, D, pivoted in like manner to the frog C; butinstead of having a pin in its short end said end is slotted, as shownin Fig. 5, and the cap-iron F has rigidly secured to it a pin, a, whichextends downward through the ordinary slot in the cutter and into theslot of the laterallyadj ust-ing lever. 'In both constructions thelaterally-adjusting lever is made to engage directly with the cap-iron,and is connected thereto by a pin-and-slot connection.

We are aware of the patents to Trau't, No. 306,877, October 21, 188i;Gage, No. 323,804, August 4, 1885, and Nicht, No. 173,177, FebruaryS,1876, and hereby disclaim all that is shown and described in saidpatents. By our improvements the construction of the laterally-adjustinglever and its connection is so simple as to be produced at the smallestpos sible cost. It is also as convenient to use as that of any'priorplane. In these prior devices when the lever or the fulcrum-block on thelever takes into the slot ofthe cuttingbit the end of the lever or blockmust be properly fitted to the slot of the cutter, and when a cutterwith a slot of different width is employed the adjusting-lever will notfit it. By our improvement different cutters may be used withoutreference to the width of the ordinary slot in the cutting-bit.

While the Gage patent shows the laterallyadjusting lever connected withthe cap-iron, it necessitates the employment of an additionalelement-viz., the fulcrum-block-not required in our combination.

In the Traut and N icht patents the laterallyadjusting lever bearsagainst the side edges of the slot in the cutter at some considerabledistance each side of a longitudinal line passing through thefulcrum-pin. In our device the bearing of said laterally-adj ustinglever on the pin which connects its slotted end with the cap-iron isnearly on said longitudinal line,

and consequently saidlever Works with greater but does not engage thecutter, substantially ease and less friction and with less Wear. asdescribed, and for the purpose specified.

We claim as our invention In a bench-plane, the laterally-adjusting le-5 Ver pivoted to the frog just underneath the cutter and connecteddirectly with the cap- Witnesses: iron by a pin-and-slot connection, thepin of JAMES SHEPARD,

which extends through the slot in the cutter, CHAS. B. STANLEY.
